Wan port question for 878 Series routers

Hello,

I am looking at upgrading a network that is using Linksys routers and sufffering from poor reliability. I want to replace them with 878 series routers as it has a built-in G.SHDSL wan port which should allow me to also remove SHDSL modems that are connected to the Linksys routers.

My question concerns the functionality of the WAN port. Some of the sites have fiber (connection to router via fiber media rate convertors) instead of SHDSL modems. If I get the Advanced IP services IOS; can I use the one of the 4 Ethernet ports on the built-in switch of the 878 to route outside/inside traffic instead of using the WAN port? Or should I purchase the 871 (Ethernet WAN port) series routers for my fiber sites?

I would like to go with a standard model for all sites, and would like to use the 878 but am worried that it won't work for my fiber sites.

These series routers are for small business solutions and most routers made for these solutions usually only have the one routable WAN port.

This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
